Also known as vaguebooking, which is defined as "An intentionally vague Facebook status update, that prompts friends to ask what's going on", but specifically refers to the more common "cry for help" type of vaguebooking.

Example:
While Vaguebooking covers all vague facebook posts such as: "That was unexpectedly splendid" or "That was unexpectedly horrible", negvaguebooking refers specifically to the negative or apparent vaguebooking cries for help:

Negvaguebooking: "That was unexpectedly horrible"

Example:

Mary: "She negvaguebooked again, once again trying to get people to coddle her."

Mark: "She was not negvaguebooking because she was more descriptive with her situation when she said "I am so mad right now at my mother" Therefore, she was merely vaguebooking. Had she just said, "I am so mad right now", that would have been negvaguebooking"
